tolong di jawab pakai cara yg benar ​

Jawaban:

1.) 3x - 2

2.) - 11y - 10

Penjelasan dengan langkah-langkah:

1. (5 - 6x) + (9x - 7)

= 5 - 6x + 9x - 7

= - 6 x + 9x + 5 - 7

= (- 6 + 9)x + 5 - 7

= 3x + 5 - 7

= 3x - 2

2. (- 2y + 8) - 3(3y + 6 )

= - 2y + 8 - 9y - 18

= - 2y - 9y + 8 - 18

= - 11y + 8 - 18

= - 11y - 10
